“…The measurements indicate that the onset of dynamical arrest and φ gel are a decreasing function of r. For r = 3.9, 8.6, and 30.1 boehmite rods, we find φ gel ∼ 1.0 × 10 −4 , 5.0 × 10 −5 , and 3.0 × 10 −5 , respectively (data not shown). These observations are consistent with those previously suggested by computer simulations and observed in experiments [42,59].…”

“…Theoretical models of aggregating particles have been developed for different mechanisms (Vold, 1959(Vold, , 1963Sutherland, 1966Sutherland, , 1967Witten and Sander, 1981;Kolb et al, 1983;Witten and Meakin, 1983;Meakin, 1983aMeakin, -d, 1984aBall and Witten, 1984;Hentschel, 1984;Meakin and Wasserman, 1984), representing two distinctly different types of particle interactions-linear-trajectory coagulation or Brownian trajectory coagulation.…”

“…For isotropic composites, fibers are initially positioned in 3D space with a derivation of a sequential packing algorithm [13][14][15]. In this process, a cylinder position is accepted if the minimum distance to any other cylinder is larger than the cylinder diameter; otherwise, the position is rejected and a new one is tested until it can be placed.…”

The influence of matrix mediated hopping conductivity, filler concentration, aspect ratio and orientation on the electrical response of carbon nanotube/polymer nanocomposites. Composites Science and Technology, Elsevier, 2011, 71 (5) This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AbstractA model to simulate the conductivity of carbon nanotube/polymer nanocomposites is presented. The proposed model is based on hopping between the fillers. A parameter related to the influence of the matrix in the overall composite conductivity is defined. It is demonstrated that increasing the aspect ratio of the fillers will increase the conductivity.Finally, it is demonstrated that the alignment of the filler rods parallel to the measurement direction results in higher conductivity values, in agreement with results from recent experimental work.
